• It is food the drives the development of new propagation techniques
• Propagation may be carried out by an array of general and specialized industries that produce plants that feed the world, provide fiber for clothing, pharmaceuticals (medicine), building materials for shelters

SEXUAL PROPAGATION
• A seed is an embryonic plant enclosed in a protective outer covering called a seed coat or testa
• Angiosperms produce plants having seeds enclosed in an ovary flowers such as marigolds
• Gymnosperms means as naked seeds they produce pine cones such as a Pine, Cedar,Ginkgo

ASEXUAL PROPAGATIONVegetative Propagation (Cloning)
ASEXUAL PROPAGATION• Fixing superior genotypes (genetic code)
• Uniformity of populations
• Facilitating propagation
• Shorten time to flower
• Control development phases
• Combining more than one genotype in a single plant
• Only means to propagate, e.g.Banana
CUTTINGS• Softwood cuttings (Herbs,
Vegetables, Houseplants and Modern Color Pants)
• Semi-hardwood cuttings (Deciduous, Evergreens and Perennials)
• Leaf cuttings (Begonia)
• Hardwood cuttings (Deciduous Plants)
• Root cuttings (Suckers)

GRAFTING
• Scion may be a single bud, small twig with several buds, a stem such as a succulent, terminal shoot in an evergreen
• Rootstock the foundation to improve vigor, change form, improve fruit bearing quality,
DIVISIONSPlant propagation by separation from parent
DIVISION• Sever from original plant
(runner) strawberry, blackberry suckers
• Simple separation of parts not rooted such as tulip bulblets or hen-and-chicks offsets
• Rough division with spade or saw canna, rhubarb or herbaceous perennials

INVITROTechnique carried out under aseptic conditions using
filtered air and sterile environment
TISSUE CULTURE• Explants are placed on solid
culture medium
• Medium contains salts plus organic nutrients, vitamins and hormones
• Medium is prepared by adding a gelling agent such as agar
• Cultures develop and grow, peeled of and subcultured
